Two charges q1 and q2 are placed at -a and a on x-axis. List-1 represent some quantities and List-2 represent their corresponding graphs. Use sign convention. In list-1 E and V represent electric field and potential and x and y represent x, y coordinates. In list-2 y-axis of graph represent E or V and x-axis of graph represent x or y coordinates.
If q1=+Q and q2=−Q, match correct option.
